Description
Technical Field
The application belongs to the technical field of mirror surface cleaning, especially, relate to a crystal growth stove window lens cleaning device.
Background
As is well known, silicon carbide is one of the important third-generation semiconductor materials, and has the characteristics of large forbidden bandwidth, high saturated electron mobility, high breakdown strength, high thermal conductivity and the like, so that the silicon carbide is widely applied to the fields of power electronics, radio frequency devices, photoelectronic devices and the like.
In the production process of silicon carbide, in order to obtain products with certain quality, the environment in the crystal growth furnace must be accurately monitored, particularly in the seeding process, the environment in the crystal growth furnace plays a crucial role in the direction of crystal lattices, and therefore the crystal growth furnace needs to be effectively monitored. In the prior art, in order to monitor the inside of the crystal growth furnace, a window needs to be formed on the crystal growth furnace, and a window lens is arranged on the window in the working process of the crystal growth furnace, so that workers and instruments can monitor the inside of the crystal growth furnace through the window lens. Because the working environment inside the crystal growth furnace is extremely severe (the internal temperature reaches more than two thousand degrees), the common lens is difficult to simultaneously meet the requirements of high temperature resistance, good light transmittance, high strength and the like, and therefore, a window lens with high price is required to meet the requirement of accurate monitoring. In addition, during the working process of the crystal growth furnace, a colored film which is difficult to wipe off and affects the observation is easily formed on the window lens, and even crystals are generated on the surface of the window lens; in order to enable the crystal growth furnace to be accurately and effectively monitored during next working, the window lens needs to be taken down to be cleaned after one-time crystallization is completed, so that the observation requirement is met.
However, it is conventional: firstly, manually grinding the window glass with grinding fluid for a long time to grind off attachments such as colored films, crystals and the like which are difficult to clean and are attached to the surface of the window glass; then, the surface is wiped for at least two times by the cleaning liquid for a long time to meet the requirement of reuse. This method has many problems, for example, because the cleaning time of each window lens is long, and the cleaning solution is easily wasted during the cleaning process, which greatly increases the cleaning cost; for another example, in the cleaning process, cleaning liquid is needed to be used for cleaning, and the cleaning liquid often contains substances harmful to human bodies, so that workers are easily injured; for another example, in the cleaning process, high-concentration industrial alcohol is needed, the requirement of the use of the industrial alcohol on the working environment is extremely high, and if the industrial alcohol cannot be effectively controlled, safety accidents are easily caused. It is worth noting that the crystal growth furnaces in enterprises often work in batches, and if the window glasses cannot be cleaned effectively in a rapid and batch manner, normal production of factories is affected. In addition, cleaning of the window lenses requires a large amount of manpower, which increases the labor cost of the enterprise.
In order to solve at least the above problems in the prior art, the applicant has proposed a cleaning device capable of cleaning the window lenses rapidly, efficiently and in batch.
The above description is included in the technical recognition scope of the inventors, and does not necessarily constitute the prior art.
